[0007] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs. The terms used in the description of the application herein are intended for describing particular embodiments only and are not intended to limit the present disclosure. In the description, claims, and the above drawings of the present disclosure, the terms "comprising" and "having", as well as their variants, are intended to convey a non-exclusive inclusion. The terms "first", "second", etc., as used herein, are intended to distinguish between different objects, rather than to describe a particular order.

[0008] Reference to "embodiments" herein implies that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present disclosure. The appearance of the phrase at various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive of other embodiments. One skilled in the art would explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0009] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0010] To address the above technical problem, according to FIGS. 1 to 6, the present application provides a flame lamp, including a main control chip 1 and at least one lighting assembly 20. The main control chip 1 is configured to generate and transmit a plurality of control signals. The number of the at least one lighting assembly 20 can be one or multiple. Each lighting assembly 20 includes a plurality of lighting structures 21. The plurality of lighting structures 21 includes a plurality of lighting elements 212 and a plurality of sub-control chips 211. Each lighting structure 21 includes respective one of the plurality of lighting elements 212 and respective one of the plurality of sub-control chips 211 electrically connected to the respective one of the plurality of lighting elements 212, each of the plurality of lighting elements 212 may be a light-emitting diode (LED) lamp bead. The plurality of sub-control chips 211 of each lighting assembly 20 are signally connected in sequence, a signal output terminal of a preceding sub-control chip is connected to a signal input terminal of a succeeding sub-control chip. The main control chip is signally connected to an initial sub-control chip of each lighting assembly 20. Each control signal emitted by the main control chip 1 is first transmitted to the initial sub-control chip of each lighting assembly 20, and then transmitted to the succeeding sub-control chip. Each sub-control chip 211 of the plurality of sub-control chips 211 is configured to respond to and execute the corresponding control signal, in this way, the plurality of lighting elements 212 can be controlled simultaneously. The main control chip 1 is configured to control each lighting element 212 of the plurality of lighting elements 212 to perform on-off variations according to a preset timing sequence, such that the plurality of lighting elements 212 can simulate a shape of a real flame. Therefore, the plurality of lighting structures 21 of a same lighting assembly 20 are connected to the main control chip 1 through only one signal transmission wire 221, which significantly simplifies the control circuit, reduces wiring complexity and a cost of wiring. Each lighting structure 21 is provided with a sub-control chip 211, such that individual control of each lighting element 212 can be achieved. Therefore, a refresh rate of the lighting element 212 can be increased, and the flame lamp can display a more refined and precise flame shape.

[0011] In an embodiment of the present disclosure, as shown in FIG. 2, at least one lighting assembly 20 is a flexible light strip 2. It should be understood that either a single flexible light strip 2 or a plurality of light strip 2 may be provided in different embodiments. Each flexible light strip 2 includes a plurality of lighting structures 21, and each lighting structure 21 is provided with a sub-control chip 211. The plurality of sub-control chips 211 in a same flexible light strip 2 are signally connected in-series, which enables the main control chip 1 to unified and orderly control all the sub-control chips 211 in the same flexible light strip 2. Since the lighting assembly 20 is configured as the flexible light strip 2 which is bendable and foldable, the flame lamp can form various shapes during installation and use, such that various demands of various uses may be satisfied.

[0012] In some embodiments, the lighting assembly 20 may be configured as a rigid lamp board or a flexible lamp board. In this case, the plurality of lighting structures 21 and the main control chip 1 are arranged on the lamp board. It should be understood that the rigid lamp board has a stable structure and may be installed easily. The flexible lamp board maintains flexibility and provides more design possibilities. The flexible lamp board is able to adapt to installation environments requiring slight bending and provide good optical performance.

[0013] In an embodiment of the present disclosure, as shown in FIG 1, the main control chip 1 is configured to generate the plurality of control signals, each control signal corresponding to one of the sub-control chips 211. The plurality of control signals collectively constitute a command packet. The plurality of control signals are transmitted sequentially within the same flexible light strip 2 according to a signal connected order of the plurality of sub-control chips 211, which refers to a physical or logical arrangement of the plurality of sub-control chips 211 in a sequential manner along the flexible light strip 2, and each of the plurality of sub-control chips 211 receives and processes the corresponding control signal in turn. In other words, after receiving the command packet, each sub-control chip 211 does not parse or execute any command immediately. Instead, the entire command packet is transmitted from one sub-control chip 211 to a next sub-control chip 211, following a sequence of the signal series connection, until the command packet reaches the last sub-control chip 211. When a plurality of flexible light strips 2 are provided, in an embodiment, a first sub-control chip 211 of each flexible light strip 2 is connected in signal parallel with the main control chip 1, which means that the main control chip 1 is connected to each first sub-control chip 211 through a same signal path. In other words, the main control chip 1 sends a corresponding command packet to the first sub-control chip 211 of each flexible light strip 2, each first sub-control chip 211 then transmits the corresponding command packet to the subsequent sub-control chips 211 in sequence. In this way, signal interference can be effectively prevented, and an electrical system of the flame lamp can be more stable and reliable.

[0014] In an embodiment, as shown in FIG. 1, after all of the plurality of sub-control chips 211 receive the command packet, the main control chip 1 then sends out a latch signal. Before receiving the latch signal, each sub-control chip 211 stores the command packet temporarily instead of parsing or executing the control signal in the packet. At this stage, each sub-control chip 211 remains in a "waiting for latch signal" state. When the main control chip 1 confirms that all sub-control chips 211 have received the command packet, the main control chip 1 sends out the latch signal. The latch signal can be a specific level signal, such as a high level or a low level. After receiving the latch signal, each sub-control chip 211 begins to parse the command packet, extracts the corresponding control signal associated with the respective sub-control chip 211, and stores the control signal into a storage unit within the sub-control chip 211. The latch signal ensures that all of the plurality of sub-control chips 211 simultaneously parsing and simultaneously storing the command packet. After the command packet has been stored, the main control chip 1 sends a display signal, which is also referred to as an execution signal. Each sub-control chip 211, based on the stored control signal, activates the corresponding lighting element 212, such as lighting up the lighting element 212, adjusting a brightness or a color of the lighting element 212. In this way, the plurality of lighting elements 212 can be simultaneously activated. The latch signal prevents each sub-control chip 211 from executing the command packet immediately upon receipt. Instead, each sub-control chip 211 holds the command packet and waits for the latch signal to trigger execution, which helps avoid timing discrepancies in execution caused by different parsing speeds among the plurality of sub-control chips.

[0015] In an embodiment of the present disclosure, as shown in FIG. 1, each control signal includes display color information for controlling a color of the lighting element 212, display brightness information for controlling a brightness level of the lighting element 212, and lighting duration information for controlling a flickering frequency of the lighting element 212. The above information enables a precise adjustment of a flame effect of the flame lamp. To be specific, the display color information specifies the color to be presented by the lighting element 212 at a specific moment, to simulate a color variation of the real flame. The display brightness information adjusts an intensity of lighting to simulate a brightness variation of the real flame. The lighting duration information determines the flickering frequency of the lighting element 212 to simulate a dynamic flame effect and imitate a movement of the real flame. By executing multi-dimensional control signals, the flame lamp is capable of producing more realistic and diverse flame effects to meet the requirements of different applications and user preferences.

[0016] In an embodiment, as shown in FIG. 1, the lighting element 212 includes a plurality of lamp beads 2121. The plurality of lamp beads 2121 can include lamp beads 2121 emitting red light, green light, and blue light. The lighting element 212 further includes a lampshade placed over the plurality of lamp beads 2121. The lampshade is configured to mix lights from different colored lamp beads 2121 by diffusing and reflecting the lights, resulting in a uniform color display of the lighting element 212. Based on an additive color mixing principle, the brightness of the different colored lamp beads 2121 is independently controlled to adjust both the display brightness and the display color of the lighting element 212. Therefore, the flame lamp is able to present a variety of color and simulate the dynamic effect of the real flame. It should be understood that, in addition to red, green, and blue light, the plurality of lamp beads 2121 can also emit lights in other colors, such as white, yellow, or orange, as long as different lights of the plurality of lamp beads can be blended to produce a desired display color of the lighting element 212.

[0017] In an embodiment of the present disclosure, as shown in FIGS. 3 to 4, a plurality of lighting elements 212 within the lighting assembly 20 together form a flame section 213. The flame section 213 includes a bottom portion 23, a middle portion 24, and a top portion 25 along a combustion direction from bottom to top. The bottom portion includes at least one bottom lighting element, the middle portion includes at least one middle lighting element, the top portion includes at least one top lighting element. The at least one bottom lighting element is configured to simulate a base portion of the real flame, the at least one middle lighting element is configured to simulate a main portion of the real flame, and the at least one top lighting element is configured to simulate a tip portion of the real flame. A layered arrangement described above allows the flame lamp to reproduce a natural appearance of the real flame more realistically. When the flame section 213 is upright, the bottom portion 23 is physically located at a lowest position to simulate the base portion of the real flame, the top portion 25 is physically located at a highest position to simulate the tip portion of the real flame, and the middle portion 24 is physically located between the lowest position and the highest position to simulate the main portion of the real flame. The flame lamp further includes a gravity sensor, which is configured to be electrically connected with the lighting assembly 20 and the main control chip 1. When the flame section 213 is suspended upside down, in other words, the bottom portion 23 is physically located at the highest position, the top portion 25 is physically located at the lowest position, and the middle portion 24 is physically located between the lowest position and the highest position, the gravity sensor can send a reversed state signal to the main control chip 1, the main control chip 1 then controls the bottom portion 23, the middle portion 24, and the top portion 25 to be logically reversed, that is, the bottom portion 23 is commanded to simulate the tip portion of the real flame , the tip portion 25 is commanded to simulate the base portion of the real flame and the middle portion 24 is commanded to simulate the main portion of the real flame. In this way, even if a physical position of the flame section 213 may be changed due to an inversion, the electrical system can ensure a visual effect of the real flame, such that the base portion the main portion, and the tip portion of the real flame can be presented in a bottom-to-top order whether in an upright state or a suspended state. Therefore, an adaptability and the flexibility of the lighting assembly 20 is enhanced, and users may use the flame lamp in different scenarios more conveniently.

[0018] In an embodiment of the present disclosure, as shown in FIG. 3, the display brightness of the plurality of lighting elements 212 increases from the bottom portion 23, through the middle portion 24, and decreases from the middle portion 24 to the top portion 25. The display color of the plurality of lighting elements 212 gradually becomes lighter from the bottom portion 23 through the middle portion 24 to the top portion 25. The variation in brightness and color is performed based on physical characteristics of the real flame. During combustion, the real flame typically appears dark red or orange at the bottom portion 23, with relatively low brightness and deeper colors. The middle portion 24 transitions to bright orange or yellow, with increased brightness and lighter colors. At the top portion 25, the real flame tends to appear pale blue or light gray, approaching white, with further reduced brightness and even lighter colors. By implementing above gradient control of brightness and color from the bottom portion 23 to the top portion 25, the flame lamp is able to simulate the dynamic variations of the real flame more realistically, such that the flame effect of the flame lamp is more natural and vivid. It is understood that such variations in color and brightness can be achieved by controlling an illumination, an extinction, and brightness levels of the plurality of lamp beads 2121.

[0019] In an embodiment of the present application, as shown in FIG. 3, during an on-off variation cycle, each lighting element 212 has a lighting ratio defined as a ratio of a lighting duration time to a total duration of the on-off variation cycle; the lighting ratio of the at least one bottom lighting element is greater than that of the at least one middle lighting element, and the lighting ratio of the at least one middle lighting element is greater than that of the at least one top lighting element. When the real flame combusting, the base portion of the real flame is more stable and sustained for a longer duration, however the main portion and the tip portion of the real flame tend to flicker more frequently, with each flicker lasting for a shorter duration. In the present disclosure, the at least one bottom lighting element has a higher lighting ratio and flickers with lower flickering frequency to simulate the base portion of the real flame. The at least one middle lighting element has a moderate lighting ratio, and flickers with a higher flickering frequency relative to the at least one bottom lighting element. The at least one top lighting element has a lower lighting ratio, and flickers with the highest flickering frequency to simulate a rapid dancing effect of the flame tip. In this way, the flame lamp is able to simulate the dynamic flickering of the real flame more realistically, creating a more layered and natural flame effect.

[0020] As shown in FIG. 4, in an embodiment, the at least one flexible light strip 2 can be folded in one plane, or at least one flexible light strip 2 can be configured as a helical structure. The bottom portion 23 includes at least two bottom lighting elements which are positioned at a same height or approximately the same height, the at least two bottom lighting elements are configured to be turned on or turned off at different time points; the middle portion 24 includes at least two middle lighting elements which are positioned at the same height or at approximately the same height, the at least two middle lighting elements are configured to be turned on or turned off at different time points; the top portion 25 includes at least two top lighting elements which are positioned at the same height or at approximately the same height, the at least two top lighting elements are configured to be turned on or turned off at different time points. When the plurality of lighting elements of the flame section are arranged along a vertical or substantially vertical direction, at least one first turning-on time difference and at least one first turning-off time difference are defined between the at least one bottom lighting element and the at least one middle lighting element; at least one second turning-on time difference and at least one second turning-off time difference are defined between the at least one middle lighting element and the at least one top lighting element, the at least one first turning-on time difference is greater than the at least one second turning-on time difference, the at least one first turning-off time difference is greater than the at least one second turning-off time difference. In this way, the flame lamp can simulate the dynamic flickering of the real flame, achieving a more natural and realistic visual effect of the flame lamp.

[0021] In an embodiment of the present disclosure, as shown in FIG. 3 and FIG. 4, when at least two bottom lighting elements of the at least one bottom lighting element are positioned at a same height or at approximately the same height in the bottom portion 23, at least two middle lighting elements of the at least one middle lighting element are positioned at the same height or at approximately the same height in the middle portion 24, and when at least two top lighting elements of the at least one top lighting element are positioned at the same height or at approximately the same height in the top portion 25, the at least two bottom lighting elements are grouped into a first bottom lighting group and a second bottom lighting group, the at least two middle lighting elements are grouped into a first middle lighting group and a second middle lighting group, and the at least two top lighting elements are grouped into a first top lighting group and a second top lighting group.

When the first bottom lighting group, the first middle lighting group and the first top lighting group are arranged along a vertical or substantially vertical direction, at least one first turning-on time difference and at least one first turning-off time difference are defined between the first bottom lighting group and the first middle lighting group; at least one second turning-on time difference and at least one second turning-off time difference are defined between the first middle lighting group and the at first top lighting group, the at least one first turning-on time difference is greater than the at least one second turning-on time difference, the at least one first turning-off time difference is greater than the at least one second turning-off time difference; or when the second bottom lighting group, the second middle lighting group and the second top lighting group are arranged along a vertical or substantially vertical direction, at least one first turning-on time difference and at least one first turning-off time difference are defined between the second bottom lighting group and the second middle lighting group; at least one second turning-on time difference and at least one second turning-off time difference are defined between the second middle lighting group and the second top lighting group, the at least one first turning-on time difference is greater than the at least one second turning-on time difference, the at least one first turning-off time difference is greater than the at least one second turning-off time difference. Such that the plurality of lighting elements 212 can be controlled in groups, therefore, the complexity in control is reduced, the dynamic flickering effect is achieved. It should be clarified that lighting elements 212 in a same group can be turned on or turned off simultaneously.
